Table 39. drives properties (continued)
Name Type Description
owner string Current owner, which is either the preferred owner during normal operation or the
partner controller when the preferred owner is offline.
• A: Controller A.
• B: Controller B.
owner-numeric uint32 Numeric equivalents for owner values.
• 0: B
• 1: A
index uint32 For internal use only.
rpm uint32 The speed of a spinning disk, in thousands of revolutions per minute, as specified by the
disk vendor. For an SSD, 0 is shown.
size string Disk capacity, formatted to use the current base, precision, and units.
size-numeric uint64 Unformatted size value in blocks.
sector-format string The disk sector format.
• 512n: The disk uses 512-byte native sector size. Each logical block and physical
block is 512 bytes.
• 512e: The disk uses 512-byte emulated sector size. Each logical block is 512 bytes
and each physical block is 4096 bytes. Eight logical blocks will be stored sequentially
in each physical block. Logical blocks may or may not be aligned with physical block
boundaries.
sector-format-numeric uint32 Numeric equivalents for sector-format values.
• 0: 512n
• 1: 512e
transfer-rate string Disk data transfer rate in Gbit/s. It is normal behavior for the rate to vary.
• 1.5
• 3.0
• 6.0
Some 6 Gbit/s disks might not consistently support a 6 Gbit/s transfer rate. If this
happens, the controller automatically adjusts transfers to those disks to3 Gbit/s,
increasing reliability and reducing error messages with little impact on system
performance. This rate adjustment persists until the controller is restarted or power-
cycled.
transfer-rate-numeric uint32 For internal use only.
attributes string Shows which controller a single-ported disk is connected to.
• A: Controller A.
• B: Controller B.
attributes-numeric uint32 For internal use only.
enclosure-wwn string Enclosure WWN.
enclosures-url string Enclosure URL.
status string Disk status.
• Up: The disk is present and is properly communicating with the expander.
• Spun Down: The disk is present and has been spun down by the drive spin down
feature.
